Bihl+Wiedemann BWU3825 Industrial Ethernet Switch

BWU3825 is an ASi-5/ASi-3 EtherNet/IP + Modbus TCP Gateway with an integrated Safety Monitor that bridges ASi fieldbuses to industrial Ethernet, while including a built‑in 2-port Ethernet switch for local network topology. It features two ASi-5/ASi-3 masters, enabling seamless connectivity to multiple ASi devices, and supports EtherNet/IP and Modbus TCP protocols for controller communication, along with an OPC UA server and REST API to enable IIoT-style data access. An integrated web server provides straightforward diagnostics and maintenance, and Safe Link technology enhances safety interoperability across the network. The gateway includes an Ethernet interface with two RJ‑45 ports and is designed for rugged industrial environments (IP20-rated housing), with ASi current monitoring and a rated current per ASi circuit to support safe operation across voltage‑sensitive devices. Use cases include connecting ASi networks to PLCs or SCADA systems, enabling remote monitoring and data exchange without compromising safety circuits, and scaling ASi installations by leveraging standard Ethernet/IP or Modbus TCP connectivity for centralized control and modern IIoT workflows. In short, BWU3825 combines fieldbus bridging, built‑in safety monitoring, and industrial Ethernet capabilities in a compact gateway to streamline integration of ASi-5/ASi-3 devices into contemporary automation architectures.
